Hi,
I am developing an application which needs to have a separate
installation for each client (i.e. Client1 will access the app via
www.mycomp.com/myapp/client1, Client2 will access the app via
www.mycomp.com/myapp/client2, etc).
However, as I understand things from the documentation for
mx:RemoteObject and LCDS, the mxmlc compiler uses context-root
property (and other properties) in conjunction with the
remoting-config.xml and services-config.xml to build your swf file,
and basically hard-codes the context root into this file. This means
that I would have to recompile the app for each client - obviously far
from ideal.
Having googled extensively, I have amended my flex code as follows to
try and get around the above issue:
<code>
...
public function init():void {
var amfChannel:AMFChannel
= new AMFChannel("my-amf", getContextRootUrl()
+ "/messagebroker/amf");
amfChannel.pollingEnabled = false;
var myChannelSet:ChannelSet = new ChannelSet();
myChannelSet.addChannel(amfChannel);
myService.channelSet = myChannelSet;
}
private function getContextRootUrl():String {
var i:int = Application.application.url.lastIndexOf("/");
var contextRootUrl:String
= Application.application.url.substring(0, i);
return contextRootUrl;
}
...
<mx:RemoteObject
id="myService"
destination="MyService"
endpoint="{getEndpointUrl()}/messagebroker/amf"
showBusyCursor="true"
result="event.token.resultHandler( event )"
fault="event.token.faultHandler( event )"
requestTimeout="30"/>
...
</code>
I have left my services-config.xml and remoting-config.xml files
unchanged:
services-config.xml:
<code>
...
<channel-definition id="my-amf"
class="mx.messaging.channels.AMFChannel">
<endpoint
url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf";
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<polling-enabled>false</polling-enabled>
</properties>
</channel-definition>
...
</code>
remoting-config.xml:
<code>
<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
class="flex.messaging.services.RemotingService"
messageTypes="flex.messaging.messages.RemotingMessage">
<adapters>
<adapter-definition id="java-object"
class="flex.messaging.services.remoting.adapters.JavaAdapter"
default="true"/>
</adapters>
<default-channels>
<channel ref="my-amf"/>
</default-channels>
<destination id="MyService">
<properties>
<source>greetingService</source>
<factory>spring</factory>
</properties>
</destination>
...
</service>
</code>
But when I run this my application just sits there with the message
"transferring data from localhost" in the browser statusbar, and I
just get the following in the server log:

I'm now completely confused - I don't know where I'm going wrong or
what to try next. Do I need to make changes to my services-config.xml
configuration? Do I still want to compile my app with -compiler option?
Perhaps I'm missing something obvious, or perhaps there is an easier
way to achieve what I'm trying to do?
Any help would be very much appreciated...
Thanks,
Lawrie.
